I know that Capita was acquired by a company called Link, and now the Capital Financial website which used to have information about what was happening with the winding up of the Arch Cru funds is now defunct. Does anyone know where the equivalent website is now located? Google hasn't been any help to me.
Thanks

If you need to ask very basic questions like this you're clearly should not be buying Thai stocks.
You'd be better off buying Thai mutual funds where you can have experts select the stocks to be held in the fund. A mutual fund will also hold dozens or hundreds of stocks, so if one company fails you only lose a small proportion of your investment.
You can open and account and buy mutual funds via your bank. After that you can buy/sell online.
Technically you're not buying from a bank, but from the bank's asset management subsidiary. They have separate websites such as:

https://www.tmbam.com/home/en/index.php
https://www.ktam.co.th/en/Default.aspx
&c.

Not studied with them, but the sample material is pretty poor. Consider the transcription system for one word:
พยัญชนะ Pá-yun-chá-ná
The letter "a" and "u" are used to represent the same vowel sound, and the tones for "pa" and "cha" are wrong for normal speech. (They should both be mid-tone, unstressed, no glottal stop.)

I'll only comment on the one site.
This is clearly not produced by anyone with scientific knowledge, and I'm pretty sure the figure is just plucked from the air.
When a site claims "bottled waters that contribute to excess body acidity" one instantly knows one is dealing with a charlatan or ignoramus. The body's pH is managed by homeostatic processes within an incredibly narrow range, 7.35-7.45. Outside that range, and you're going to be severely unwell or dead.

The home page of the website further proves it to be run by quacks and snakeoil salesmen.
"Detoxify" - nobody can actually say what these so-called "toxins" are. They are not something scientifically recognised. They're just all woo.
"Antioxidants" - the body is already packed with natural antioxidants. Consuming food with antioxidant properties has no detectable effect on the lefts of antioxidants in the body. It's also questionable whether oxygen and hydrogen even act as antioxidants in the body as is claimed.
"Water ionizers create high alkaline and low pH water" - utterly impossible for water to be both highly alkaline (high pH) and low pH at the same time.

Not quite. Safe to drink when it leaves the production plant. However, not necessarily safe to drink when it comes out of your tap because of pipe leaks along the way allowing bacteria to enter. And the state of water infrastructure in Bangkok is parlous. Quite possibly worse in other provinces.

It's not possible to be "fully protected" with Microsoft Windows.
I recently had the misfortune to use a friend's Windows computer. It was running Microsoft Security Essentials which didn't report any problems, though the browsers had clearly been hijacked by mail.ru-type malware.
Comodo was able to partially clear the malware, but something was left which Bitdefender could detect, but couldn't clean. Malwarebytes and Panda Cloud Antivirus were ineffective.
No anti-malware programme is going to be 100% effective. And with an incredible 350,000 new Windows viruses emerging every single day*, that's pretty much inevitable.
